Canadian Refinery to Use Ultrafiltration, Membrane Bioreactor Tech to Recycle Water
North West Redwater (NWR) Partnership's Sturgeon refinery in Alberta, Canada, will use ultrafiltration and membrane bioreactor technology to meet sustainability and environmental goals.
NWR sought out the filtration water treatment technology from GE's Water & Process Technologies to reduce its use of water in the refining process and minimize its environmental impact on the North Saskatchewan River. Alberta has stringent regulations regarding freshwater withdrawal and effluent discharge.
To minimize the use of freshwater, the ultrafiltration and membrane bioreactor technology will treat and recycle the process waters from the refinery multiple times. Surface water runoff from the facility will be contained in the retention ponds and used for process purposes to reduce the water withdrawal from the river. Chemistry and on-site technical support from Water & Process Technologies will help ensure that the facilities' water balance targets are met and maintain the reliability of its assets by protecting from deposition and corrosion.
The Sturgeon refinery project, which is expected to be operational in 2017, was designed to incorporate gasification and a carbon capture and storage solution while producing the cleaner, high-value products needed to meet North America's low-carbon standards. Phase one of the Sturgeon refinery will process 50,000 barrels of bitumen per day.
